游戏开始后，屏幕每隔一秒，就会生成一个小行星。我们要用鼠标点击小行星，飞船会射出子弹击爆小行星，如果未能在十秒内击爆小行星，那么游戏就会失败。击爆所有小行星后，游戏就会胜利。

Once the game starts, every second on the screen, an asteroid will spawn. We have to click on the asteroid with the mouse, and the ship will shoot bullets to blow up the asteroid, and if we fail to blow the asteroid in ten seconds, then the game will fail. Once you blast all the asteroids, the game wins.
